Iphone 4s Alarm Clock

I have been using my iPhone for my wake-up alarm beginning with the original iPhone followed by the the iPhone 3G, an iPhone 4, and now with an iPhone 4S. I've never had a problem with an alarm going off with any of my iPhones and with every iOS version beginning with 1.0. My 4S is running 5.0.1.

Did you transfer the backup for another iPhone or iOS device to your iPhone 4S?

Has not failed for me once M-F every week since 6/30/07 - I purchased the original iPhone on the release day the day before.

Probably just an initial glitch, but it can't hurt to use what you were using as an alarm clock before the iPhone for a week or so to be more trusting of it.

You did have the volume turned up?

I use my iphone M-F as an alarm clock, only glitches I have is either forgetting to set the alarm or having it set to p.m instead of a.m..

When you set your alarm tonight you should see a clock at the top right hand corner next to your battery life.

Never had any problem either using it (unlike other 3rd party alarm apps). That's my 2 cents to try to find the problem.

The silent switch being on does not prevent an alarm from sounding, but you can have the volume level turned down.

I have had the same problems whereby the alarm did sound on the 1st day of setting but not for the other days set in the repeat list.

My phone was switched off but I thought the alarm would wake the phone up and sound the alarm. I have just tested the alarm with the phone in standby mode and it did sound; maybe this is the way forward but it obviously effect the battery life.

Off means off. A computer cannot wake up when off and the same with the iPhone.

If you are worried about battery consumption, connect the iPhone to a power source at night and then you will have a fully charged battery when beginning each day or after the alarm sounds, or enable Airplane mode which is a very low power mode since all radios are off.

This is a thing. My iPhone 5 has been doing this as well. It's not turned off, it's not muted, I'm not doing anything weird, and I have been using the alarm to wake me up for years. As of late, though, every so often I'll wake up on my own, look over, and see that my phone has an "Alarm" notification on the screen but is completely silent. I'm not sure, but it also seems like the battery has been drained more than usual as well.

There are comments like this all over the internet, so there's clearly some sort of issue here. I just wish I could find a place that had some kind of solution instead of a bunch of people saying "I don't have that problem." 😟

There was a specific issue with repeating alarms about a year ago that had a short term fix of deleting the alarms and readding them. It was resolved by one or another update. Unlike your issue, the alarm simply didn't go off. You may want to start a new thread with your issue, which seems to be one in which the alarm went off as intended but there was an issue with the sound.

Best of luck.

I have been having the problem of every three days or so my phone goes into silent mode and the only way to get sound back is to reset I upgraded from a 4 to a 5 and same problem I was using an alarm clock called nightstand pro so I thought I would change to a different alarm clock and have not had an issue in over a week I cave contacted their support hope they can fix.

Hope this helps people with same issue
